EnCana unveils The Bow - Calgary's newest tower

CALGARY, Alberta (October 12, 2006) - EnCana Corporation (TSX, NYSE: ECA) today filed a development permit application with the City of Calgary for the construction of The Bow, Calgary's newest office tower. EnCana, along with its architectural team led by Foster + Partners, unveiled the design for the spectacular 59-storey glass and steel office high-rise to be built in the heart of downtown Calgary.

Configured in the shape of a bow, the 1.7 million square foot tower is a striking creation that provides office occupants an expansive view of the surrounding environment - Rocky Mountains and the Bow River Valley to the west, the Canadian Prairies and Bow River to the east. Located between 5th and 7th Avenues between Centre and 1st Street S.E., the new building design features three interior garden atriums up the west face of the structure.

"We believe our dramatic new office tower will be a premier Calgary workplace, one that will enhance staff recruitment and retention while creating an energetic urban village in our city's core. Our people will enjoy multiple advantages by being housed in a single location along with amenities such as indoor gardens, a public outdoor space, complementary retail businesses and vibrant cultural venues. The innovative design of Foster + Partners will only enhance the EnCana work experience," said Randy Eresman, EnCana's President & Chief Executive Officer.

"Beyond the benefits to the EnCana workplace, we believe The Bow reflects the growing importance of our city and province from a business and cultural perspective. At EnCana, we are proud to play a role in adding exceptional architecture to our city skyline, as well as invigorating the centre of Calgary," Eresman said.

The Bow will set a new standard for environmental sustainability among high-rise offices in Canada. For example, the aerodynamic design of the crescent-shaped tower reduces the structure's wind load, thereby reducing the amount of structural material required and the surrounding turbulence. At the same time, the south-southwest orientation makes efficient use of the southern Alberta sun. The energy efficient design, which employs natural light and ventilation, is expected to reduce energy use by about 30 percent, compared to a conventional tower.

"EnCana's building project team has focused on creating a pleasant and efficient workplace that is tailored to support our individual business units. By initiating the design and development, we hope to bring greater certainty to our long-term occupancy costs in a competitive commercial real estate market. While we do not plan to own the building and we have conducted market research into selling it prior to the construction start, we do plan to be The Bow's long-term, principal tenant," said John Brannan, EnCana's building project executive lead.

EnCana hopes to receive development permit approval from the City of Calgary in the spring of 2007, and construction is expected to start shortly thereafter. EnCana plans to start occupying the building in the third quarter of 2010, with final occupancy in 2011.

Matthews Southwest of Toronto and Dallas is the lead project developer, managing site acquisition, architectural design, City of Calgary permits, and development planning strategy. Foster + Partners of London, England is the signature architect and Zeidler Partnership of Calgary is the project architect. In addition, EnCana retained Jeremy Sturgess of Calgary's Sturgess Architecture for the master planning of the streetscape and urban design.
